Attribute/variable scope in dynamic components

[MikeWayzovski]

The Dynamic Components range is set by its context: see this thread:

Attribute Scope

In general, the scope of a components attribute is three levels: one up, one down and the context level where it resides. Consider the model (drawing), level 0. Then, the deeper the nested components the higher the level of indention will be. There is a way. All nested components should have the same named attribute and a formula that refers to the parent (e.g. popvar=PARENT!popvar) That way, only the highest level components have to get the value from a ‘sibling’ and all the deeper levels wi…

How accessing Model attribute from Components?

You can make a ‘swatch’ component (just some geometry) and add attributes to them which can be used by other components. DC can read attributes of other groups/components which are: one level down , same level, or one level up. Consider the Model to be the top level (=level 0) and residing components level 1, the nested components in level 1 components are level 2 , etc. This means that for instance level 5 components should somehow ‘inherit’ attributes from the higher levels ( where 0 is top a…

The trick is to create a ‘swatch’ or dummy component with the right attribute…
